What makes REZ different
REZ is short for resurrection: a fresh start for how you eat, train, and feel. Nutrition, supplements, workouts, and a muscle heat map in one app, with or without an account.
DownloadFeatures
Focus Dashboard
Build your own home screen from swappable blocks: calories, macros, water, sleep, supplements, workouts, weight, and streaks.
Pull-Down Quick Log
Pull down from the top of Focus to log food, water, workouts, weight, sleep, or scan a barcode without leaving the dashboard.
REZ AI Food Log
Talk or type what you ate. REZ asks quick follow-up questions, matches real foods, and logs the meal for you. (Pro)
Search, Scan & Restaurants
Search the REZ Foods catalog, scan barcodes, build restaurant combo plates, and customize drinks by size and add-ons.
Smart Nutrition Goals

Supplements & Micros
Schedule supplements on intervals or on/off cycles, check off doses, get reminders, and track the micronutrients you care about.
Allergen Alerts
Set your allergens once and REZ flags matching foods in search, barcode scans, restaurant menus, and your food log.
Splits & Set Logging
Build workout splits, log sets, reps, and weight with a rest timer, plate calculator, supersets, and progressive-overload nudges.

Apple Health & Health Connect
Sync active energy, steps, sleep, heart rate, resting heart rate, and body weight from Apple Health on iPhone or Health Connect on Android.
Focus
Focus is your home screen, built from blocks you choose: calories, macros, water, sleep, workouts, weight, streaks, and charts. Arrange them however you like, and swipe the date to look back at any day.
The pull-down tab is the fastest way to log anything in REZ. Pull down from the top of Focus and a quick log panel drops in with a tile for everything you track, so you can log in a few taps and get back to your day.
How the pull-down tab works
Pull down
Drag down from the top of Focus. On iPhone the panel opens as soon as you pass the edge, no need to let go.
Pick a tile
Food, Water, Workouts, Weight, Scan, plus a tile for every other tracker you have turned on.
Log it
Enter the amount and submit. Entries land on the day selected in your Focus calendar, and the panel closes itself.
Pull-down tiles
- Food: search, quick input, or REZ AI
- Water in ml or fl oz
- Workouts: search, recent, the REZ library, or calories burned
- Weight and body fat %
- Sleep, steps, heart rate, and meditation
- Micronutrients
- Barcode scan
Made to fit you
- Only the trackers you turn on show up as tiles
- Choose whether Food opens in search or quick input
- Log to today or any past day from the calendar
- Home Screen widgets and Siri can jump straight to a tile on iPhone
- Tap outside the panel to close it
Pull down on every tab
- Nutrition: calories left, macros, water +250 / +500, supplements due, quick add, and today’s log
- Type commands like “water 500” or search 90 days of food history
- Workout: today’s split, exercises due, your splits, and tools like the plate calculator and muscle map
Food Logging
Logging food should take seconds. With REZ AI you just say what you ate, the way you would tell a friend: “two eggs, toast with butter, and a black coffee.” REZ asks a quick follow-up only when it needs one, matches each item to a real food, and builds the meal for you to confirm.
No guesswork and no hunting through search results. Nothing is saved until you tap Log, and every item can be adjusted first. Prefer to do it yourself? Search the catalog, scan a barcode, build a restaurant plate, or reuse your saved meals.
How REZ AI works
Say it or type it
Open REZ AI from the Food tile in the pull-down or the ✨ button on any meal. Talk in English or Spanish, or switch to typing.
Answer a quick question
If something is unclear, REZ asks one short question at a time, like the portion size, combo or single item, or which drink came with it.
Check the match
Each item is matched to a real food from the REZ catalog. Tap Looks good, or Wrong item to fix it.
Review and log
See calories, protein, carbs, and fat, plus salt, sugar, and fiber when known. Adjust anything, pick the meal, and tap Log.
Every other way to log
- REZ Foods catalog with verified foods
- Barcode scanner
- Recent foods and “Log again” from your history
- Saved foods and meal groups
- Pick several foods and log them as one meal
- Quick input for calories and macros by hand

Nutrition
The Nutrition tab is your day at a glance: calories eaten and remaining, protein, carbs, and fat, and a food log split into breakfast, lunch, dinner, and snacks. Tap a food for its full breakdown, hold to edit it, or swipe to delete.
Turn on only the trackers you care about and each one gets its own section: water, supplements, micronutrients, sleep, meditation, and heart rate.
How your goals are set
Your BMR
Calculated from your profile with Mifflin-St Jeor, Harris-Benedict, or Katch-McArdle, or enter your own.
Maintenance
Your BMR multiplied by your activity level, from sedentary to extra active.
Your goal
Cut or bulk by 250 to 1,000 calories a day, or maintain. A custom calorie goal always wins.
Your macros
Protein is set first from your weight and goal, then fat and carbs fill the rest. Override any of them.
Micronutrients
- 19 vitamins and minerals to choose from
- Set a minimum or maximum target for each
- Totals from meals, supplements, and manual adds
Water, sleep & more
- Water in ml or fl oz with a daily goal
- Optional morning, afternoon, and evening water targets
- Sleep with a 7-day chart
- Meditation and heart rate
- Apple Health and Health Connect imports
- Meal-time windows you can edit
Supplements
Supplements live right inside Nutrition. Add each one once with its dose and schedule, and REZ keeps track of what is due, what you took, and what you missed, whether it is a daily vitamin, a weekly injection, or something you cycle on and off.
Doses due today show up on the Nutrition tab and in its pull-down, so checking one off takes a single tap. Any micronutrients a dose provides count toward your daily targets.
How supplements work
Add it
Name it, pick oral, injection, or topical, and set your dose. Add the micronutrients each dose provides if you want them counted.
Set the schedule
Every few hours or days, on/off cycles with a start date, or as needed, with an optional dose time.
Check it off
Due doses appear on the Nutrition tab and in its pull-down. One tap logs the dose.
Stay consistent
Hold a supplement to see your adherence and streak over the last 60 days, fix past days, and check your inventory.
Schedules
- Interval: every hour up to every 60 days
- On/off cycles: days on, days off, and a start date
- As needed, with no schedule
- Optional fixed dose time
- Missed a dose? Keep the scheduled day or restart from the day you took it
Reminders & inventory

- Low inventory flag before you run out
Insights
- Estimated adherence and streak over 60 days
- Calendar of logged doses

- Pro syncs your schedules across devices
Analytics
Every number in REZ has more behind it. Press and hold a card on Focus, Nutrition, or Workout to open its analytics: averages, trends, streaks, and history, right where you are.
Add chart blocks to Focus to keep your trends on your home screen, and use the calendar to see at a glance which days you hit your goals. Analytics are free for everyone.
How it works
Press and hold
Hold any card, like calories, water, sleep, weight, a supplement, or an exercise.
Pick a range
Switch between today, this week, and this month, or 1M, 3M, 6M, and all time for lifts.

Workout
Build your training around splits: named groups of exercises like Push, Pull, or Legs. Pick exercises from the REZ catalog or create your own, tag the muscles they work, and REZ shows you what is due each day.
Every exercise has its own tracking type, so logging fits the movement: sets and reps for lifts, a countdown or stopwatch for timed work, or a single tap for anything you just need to check off.
How a workout goes
Open today’s split
The Workout tab shows what is due today, with last session’s numbers ready to beat.
Log your sets
Enter reps and weight, or tap Copy last. A rest timer starts between sets.
Take the nudge
REZ suggests your next set: more weight when you hit your reps, or one more rep when you don’t.
Finish strong
Complete the session to save it, see your new PRs, and keep your streak going.
Split types
- Weekly schedule: drag splits onto weekdays, open days are rest days
- Rotation: splits run in order, with rest days wherever you place them
- Stack two splits on one day, like Push + Pull
- Swap today’s split or skip an exercise just for today
- Supersets and combos that group several movements
Tracking types
- Sets & reps
- Countdown: finish before it hits zero
- Stopwatch, with optional extra weight like a vest
- Just mark done: one tap repeats your last session
Set options
- Warm-up sets that don’t count toward PRs
- Load types: total, per side, body weight, assisted, or added load
- Optional RPE from 6 to 10
- Notes on each exercise, like seat height
- Plate calculator that fills in the weight
Progress

- Workout streak and weekly plan progress
- Body-weight goal and optional strength score
- Calories burned from exercises, workouts, and health apps
Heat Map
See your training on an interactive 3D body. REZ reads your splits and the last 7 days of workouts and colors every muscle, so it’s easy to spot what you train often and what you skip.
Drag to rotate, pinch to zoom, and tap a muscle for weekly sets, training days, and when you last hit it. Every muscle lists the workouts that train it and suggests exercises you can add to a split in one tap.
- CoverageMuscles your splits train, plus muscles hit only by workouts from the last 7 days.
- ActivityEach muscle fades from bright to neutral over 14 days since you last trained it.
- ExploreA clean body to tap, rotate, and inspect any muscle.
How the heat map works
Tag your exercises
Every exercise belongs to a muscle group, and you can tag the specific muscles it works too.
REZ adds it up
Planned sets from your splits count at half weight and sets logged in the last 7 days count fully. Warm-ups are left out.
The body lights up
10 effective sets a week means a muscle is well covered. Fewer is partly covered, and none is not targeted.
Fill the gaps
Tap a muscle to see what trains it, then add a suggested exercise to a split in one tap.
Muscle details
- Effective sets per week, training days, and last trained
- Weekly coverage percentage
- Every workout that trains it, marked primary or secondary
- Suggested exercises from the REZ library
- A list of muscles nothing in your plan trains
The 3D body
- 36 muscles, with left and right sides tapped separately
- Drag to rotate, pinch to zoom, tap to inspect
- One tap back to the front view

Widgets
Your day at a glance, without opening the app. REZ puts calories left, macros, water, and today’s split on your Home Screen and Lock Screen, with buttons that log water in one tap.
During a workout, Live Activities keep your rest timer and stopwatch on the Lock Screen and in the Dynamic Island, with buttons to log your next set, start a rest, or finish the session without opening the app. And when your hands are full, just ask Siri.

Apple Health Sync
Connect Apple Health once and REZ fills in your day for you. Calories your Apple Watch burned, your steps, sleep, heart rate, and smart-scale weigh-ins show up next to the food and workouts you log, so your calorie budget and analytics reflect your whole day.
You stay in control. REZ only reads the data you allow, never writes to Apple Health, and never replaces numbers you entered yourself.
How to turn it on

Go to Settings → Add-ons in REZ, or turn it on during first-time setup.
Turn on Apple Health
Flip the Apple Health switch and choose what REZ can read in the iOS permission screen.
